[0033] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0034] The components of the embodiments of the present application described and illustrated herein can be arranged and designed in a wide variety of different configurations. Therefore, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, but is merely representative of selected embodiments of the application.

[0038] As Figure 1 shown, when testing the existing vehicle-mounted visual controller, it needs to be connected with the car screen of the car machine, communicate through the car machine, receive video signals from each camera on the car machine, and display on the car screen. At the same time, the vehicle-mounted visual controller will also be connected with the debugging tool through the serial port, and the tester will send instructions on the debugging tool to control the test process, and then visually judge the video results displayed on the car screen. The auxiliary tools required for the whole test are complicated, and the test results are determined by the human eye, and the results are not reliable.

[0039] The vehicle-mounted visual controller test interface framework of the present application is shown in Figure 2 by configuring the environment of the upper computer, and then using the multimedia player loaded in the upper computer to acquire the video stream data of each camera in the vehicle-mounted visual controller, which replaces Figure 1The vehicle machine and the vehicle machine screen in the vehicle machine and vehicle machine screen, and the whole test process is controlled by using a script, without connecting a serial port, and the test result document can be automatically generated, so that the whole test is automated, the hardware used for testing is saved, and the testing cost is saved.

[0040] Next, the technical solutions of the application will be described in specific embodiments.

[0041] Embodiment 1

[0042] As shown in the figure, the vehicle-mounted visual controller test method of the application includes the following steps: Figure 3

[0043] Step S100, establishing the connection between the host computer and the vehicle-mounted visual controller.

[0044] The vehicle-mounted visual controller is used for intelligent cabin full-scene, covering the driver monitoring system, rear blind area monitoring system, passenger monitoring system, visual interaction system and the like. Therefore, the vehicle-mounted visual controller needs to receive and process the video data of multiple cameras connected thereto, and needs to provide a real-time data stream with high enough quality to ensure the real-time and effectiveness of the data. For example, for the driver monitoring system, the state of the driver needs to be monitored in real time to determine whether the driver is driving in a normal state, so real-time video information needs to be obtained for background analysis and operation.

[0045] Therefore, the stability of the RTSP real-time data stream of the vehicle-mounted visual controller needs to be tested.

[0046] The application connects the host computer and the vehicle-mounted visual controller, establishes a network connection between the host computer and the vehicle-mounted visual controller, and realizes that the host computer can obtain the real-time data stream in the vehicle-mounted visual controller.

[0047] In the application, the host computer is taken as an example of a PC, and the PC and the vehicle-mounted visual controller are connected through a network port, that is, a simple local area network is established between the host computer and the vehicle-mounted visual controller, and the host computer can be considered as the master and the vehicle-mounted visual controller as the extension in the subnet.

[0048] In order to ensure the test environment, the host computer is equipped with a virtual machine of Ubuntu, so as to provide a pure test environment and simulate the actual running environment as much as possible.

[0049] ​The network segment of the gateway connected by the PC and the vehicle-mounted visual controller is set to the same network segment, so that the network connection of the PC and the vehicle-mounted visual controller is realized. The connection mode can be connected through the USB network card and the PC USB interface, and then connected through the matching data line, the network port and the vehicle-mounted visual controller, to form a local area network. The network interface of the vehicle-mounted visual controller can also be directly connected to the network card integrated with the PC through a network cable, to form a local area network.

[0050] After the connection is successful, the host computer can obtain the video data captured by the camera connected to the vehicle-mounted visual controller by accessing the address, so as to simulate the working environment of the vehicle-mounted visual controller in actual work.

[0051] In step S200, the video player in the host computer is started through an automatic test script, so that the video player accesses the vehicle-mounted visual controller to obtain a video data stream, and records the returned test data.

[0052] The automatic test script is written to realize the automatic test of the vehicle-mounted visual controller. The script runs in the Ubuntu virtual machine described above. The script can be a script written in shall language. Different scripts are selected for testing according to the test content and the test equipment. For example, stress test, compatibility test, delay test, coverage test, etc. The stability of the vehicle-mounted visual controller is determined through different test methods.

[0053] The script starts the video player in the host computer according to a certain logic, accesses the camera address of the vehicle-mounted visual controller through the video player, and establishes a communication connection with the camera. In this way, the image video data captured by each camera in the vehicle-mounted visual controller is transmitted to the video player and displayed in the video player. The state parameters of the corresponding camera can be obtained, which can reflect whether the real-time data stream transmission of the vehicle-mounted visual controller is stable. Therefore, these data are saved as test data for the generation of the test result document.

[0054] In an optional solution, the video player can be a VLC multimedia player, and the vehicle-mounted visual controller can be equipped with multiple cameras, such as six cameras, and then multiple VLC multimedia players can be opened to access the addresses of the six cameras respectively to obtain the real-time data streams of the cameras. Since the real-time data streams transmitted by the cameras to the host computer are transmitted through the vehicle-mounted visual controller and completely follow the program logic inserted in the visual controller, the connection success or failure, connection rate, delay, connection time, connection duration and other state parameters can be obtained by searching for keywords, and these parameters can be used as test data to determine whether the vehicle-mounted visual controller is stable after the test.

[0055] For example, in a stress test, the number of accesses to the cameras can be set to multiple times, and the cycle period of each access can be set. According to the cycle period and the number of starts, the video player is started periodically to frequently connect to the cameras.

[0056] In a feasible embodiment, the number of accesses can be set to 100, and the cycle period can be set to 5 seconds. Then, the video player accesses the cameras every 5 seconds for a total of 100 times. Taking a vehicle-mounted visual controller with six cameras as an example, the addresses of the six cameras are accessed in the above manner, 100 times for each camera and 5 seconds for each access interval. By adjusting the cycle period, the access frequency during the test can be adjusted to adjust the access pressure, and then the pressure limit can be measured.

[0057] The state parameters include connection success, connection failure, connection time, connection duration, camera address and error parameters corresponding to the camera that fails to connect.

[0058] The connection success means that the video player obtains the data of the camera, and the connection failure means that the data transmitted by the camera cannot be obtained, which can be due to a timeout or a completely inaccessible network.

[0059] The connection time represents the time from initiating the access request to obtaining the data, and the connection duration represents the duration of maintaining the connection, which usually does not exceed the cycle period. In addition, when the connection fails, the error parameters corresponding to the camera that fails to connect are also returned.

[0060] The error parameters are error parameters of the type that causes the connection failure, which can be obtained from the serial port print of the vehicle-mounted visual controller by extracting the error parameter keywords. The error parameters can be used by developers to find the causes of the errors.

[0061] Step S300, according to the test data, generate a test result document, according to the test result document, draw the real-time streaming stability of the vehicle-mounted visual controller.

[0062] After obtaining the test data, according to the test data, generate a test result document, specifically, the test data in this test result document is recorded according to the time sequence of the test and the different addresses of the cameras.

[0063] Still taking the case of 6 cameras as an example, the test data generated in the first access will have 6 groups, then the 6 groups of data are arranged in the order of the first camera to the sixth camera, and then the test data generated in the second access, and so on, until the test data generated in the last access. At the same time, for each access, there is a serial number indicating the number of accesses, and the number of successful connections and the number of failed connections in the entire test are counted.

[0064] Among them, the number of failed connections and the number of successful connections can be found by keyword query, and these keywords are related to the specific connection protocol, such as "access fail" or "access success" and the like.

[0065] It can be understood that when high-frequency connection and disconnection operations are performed on the cameras in a short period of time, great pressure will be caused to the entire communication line, and temporary connection failure may occur from the software and hardware levels. Therefore, according to the number of failed connections of the cameras, the connection failure rate in this test can be obtained. If the connection failure rate exceeds the preset value, it is determined that the vehicle-mounted visual controller is unstable.

[0066] It can be understood that the preset value is also related to the project being tested, for example, in the stress test, the failure rate can increase as the cycle time decreases, or it can increase as the number of starts increases.

[0067] Among them, for different cameras, the failure rate needs to be calculated separately, for example, if there are 6 cameras, there will be corresponding 6 failure rates, so as to reflect which cameras are unstable in connection and which cameras are stable in connection. To determine the stability of the vehicle-mounted visual controller.

[0068] It can be understood that the above test process does not require the tester to distinguish the video by visual means, and the playing time of each video can be shorter. The program can determine whether the data is received from the data stream itself, thereby serving the pressure test with a shorter cycle period and other tests, making the entire test process automatic, and reducing the need to use the screen and other hardware of the vehicle machine when testing the vehicle video controller, so that the test environment is simpler.
